So I'm planning a far future scale modeling project that needs a tube 1.5" in diameter. I immediately thought of 38mm couplers, but I need it in 15.5 inch sections. Does anyone sell cardboard 38mm couplers in longer sections? The only one I've found is Blue Tube which I'd rather avoid as this isn't a high stress component and I'm right on the edge of enough railspeed as it is, so the extra weight hurts.

If you contact Loc I believe they will sell you a full length of 38mm coupler stock. Depending on dimension of the scale a full section of BT60 coupler from BMS is a possible option as well and slightly lighter weight too.

Loc Precision will have them. The 38mm MMT in the Forte alone is something like 24"
Thanks all!

Sounds like contacting LOC is the best option. BT-60 couplers are too big, but Semroc BT-58 coupler would be even better- anyone sell that in larger lengths?
